Recall three things about acceleration: * a curved trajectory requires a (centripetal) acceleration * acceleration is a vector; it has a direction and a magnitude * the magnitude of the acceleration is a = F/ m Recall that a charged particle, moving at velocity v perpendicular to a magnetic field, experiences a transverse force F=qvB. Recall also that charged particles can be either positive or negative. Using pencil and paper, combine the two formulas above to obtain a formula for...

Five particles follow the paths shown in the figure as they pass
through a magnetic field B, which is indicated by the dots or x's
in the figure (dot = out of the page, x = into page). What can you
conclude about the charge of each particle? (If your answers for
charges of particles 1, 2, 3, 4, and 5, are, respectively, +, 0, +,
-, 0, then enter: +0+-0 into the computer.)
Charged Particles Moving in a Magnetic Field Ranking Task
Five equal-mass particles (A–E) enter a region of uniform magnetic field directed into the page. They follow the trajectories illustrated in the figure. Which particle (if any) is neutral? Which particle (if any) is negatively charged? Rank the particles on the basis of their speed.

The number of particles emitted from a radioactive source during a specified period is a random variable with a Poisson distribution. If the probability of no emissions is 1/3, what is the probability that 2 or more emissions occur? ans: 2−ln 3 / 3 .

Which property is observed when a beam of charged particles is fired into a magnetic field?...
Which property is observed when a beam of charged particles is fired into a magnetic field? If the beam of charged particles is parallel to the magnetic field, no deflection will occur. The maximum deflection happens when the beam is perpendicular to the magnetic field. The magnitude of the magnetic deflecting force is directly proportional to the magnitude of the charge on each particle. The magnetic deflecting force is always perpendicular to the direction of travel of the charge and...
